BOOK oovna Application filed April 18,

The present invention relates to book covers. The sides of book covers are usually made of cardboard or like material, provided at .5 their outer faces with a covering of paper, cloth, leather or some other suitable sheet material. When books are subjected to hard usage, the free corners of the cover sides thereof suffer in that not only the covering material is worn away at the said free corners but also the cardboard. When this happens, the free corners of the leave-s within the book cover are injured and gradually worn away. I w

The main objectof the present invention is to provide a book cover, wherein the free corners of the sides thereof are protected against hard usage, or, in other words, to produce a book cover, the corners of which are re-enforced.

Another object of the invention is to provide a book cover of the type mentioned which is simple in construction, durable in use and capable of manufacture on a comiiiercial scale, or in other words one which is not so difiicult to make as to be beyond the reasonable cost of such an article.

With these and other objects in View, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claim and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claim, without departing from the spirit or sacrificing any of the advantages of the invention. I

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a book cover constructed. in accordance with the present invention; Fig. 2 is a section taken on line 2-2 of Fig. 1, on a larger scale; and

of the re-enforcing means detached from the book cover.

In the drawings, the numerallO indicates one of the sides of a book cover, the same being oblong in configuration and consisting of a base 11 of cardboard or the like, provided around each of its free corners with an L-- shaped notch 12, which is adapted to receive a corner re-enforcing element, as will hereinafter appear. The cover side is provided with an outer covering 13 of suitable sheet material, whichis folded aroundthe free edges of the side onto the inner face thereof, as indicated at 14. Onto the inner face of the cover is glued an inner covering 15 on top of the folded over portions, is of the outer covering 13.

Into each notch 12 is fitted an L-shaped re-enforcing element 16, completely filling said notch and being of a'thickness corresponding to the combined thicknesses of the cardboard base 11 and the inner and outer coverings thereof. This re-enforcing element is made of some suitable hard substance, such as fiberboard, vulcanized fiber, hard rubber or the like, that is to say of some material that will withstand hard usage. The ends of each re-enforcing element are wedge-shaped, as shown at 17, and the endslSof the notches 12 are similarly shaped, so that the re-enforcing elements are properly kept in place. For the purpose of anchoring these re-enforcing elements, there is formed in each leg of the same an aperture 19 in alignment with a re cess 20 in the cover side, and through each aperture is driven into the registering recess a feather or tongue 21. As appears from the drawings, these tongues are substantially wedged-shaped, so that, in driving the same home, they will properly fix the re-enforcing elements in position upon the cover side. The tongues are made of some suitable rigid material and have glue applied thereto before being driven through the re-enforcing element into the cover side. The purpose of this is obvious.

The re-enforcing elements are preferably of the color of the outer covering of the cover side. If necessary, a substantially triangular sheet 22 may be fitted over each re-enforcing element and the adjacent portion of the outer covering 13, to ornament the cover side or to conceal the said re-enforcing elements.

The re-enforcing elements protect the cover corners and the leaf corners against hard usage.

What- I claim is A book cover side provided around each free corner thereof with an L-shaped notch,

each notch end being undercut so that the cover side material overhangs the end of the notch, an L-shaped re-enforcing element fitted into and completely filling each notch, the ends of each re-enloreing element being wedge-shaped and placed into the undercut ends of said notches whereby the cover side material overlying the triangular ends of the notches prevents shifting of the re enforcing elements both laterally and longitudinally of the cover side, each L-shaped element being provided in each of its legs with an aperture in alignment with a recess in the cover side, and a wedge-shaped tongue driven through each of said apertures into the respective reeess.
